- mmnr'ue momma Application filed zuia,

This invention relatesto machines forbandmg cigars and similar articles and has for its object- 'to secure the overlapping ends of a band or the like in a rapid and eflicient man- Two methods have heretofore been used in banding cigars. In one method bands having dried gum, paste or the like at one end are used, the gummed end being moistened shortly before the ends are pressed together. In the other method wet paste is applied-to an ungummed band just prior to the banding operation. In either of these methods an appreciable time is required for the wet adhesive material to become dry enough to hold. The result has been that some of the bands fail to remain on the cigars. Both of these methods have other objectionable features which are avoided by the use of this invention.

In accordance with the invention gummed bands are used and are wrapped about the cigar, preferably with the gummed end unmoistened. The ends are simultaneously pressed together and heateclto a point where 5 the gum is softened enough to quickly and ermanently adhere to the ungummed surace. I have found in the case of bands which are now on the market that this result can be accomplished by the use of'a very moderate degree of heat, not sufficient to injure either the cigar or the band.

The invention will be more fully understood by reference to the'following detailed description and claims taken in connection with the accompanying drawings,vin which: Figure 1 is an elevation of a portion ot a cigar banding machine showing how the 1nvention is incorporated therein and F i are 2 is a detail view of a roller and associated elements used in Figure 1.

Figure 1 shows an arrangement of certain parts of a banding machine which is shown in its entirety in myapplication Serial Number 3,924, filed January 22, 1925. Only such parts are illustrated herein as are necessary to an understanding of this invention. The essential parts are briefly, a su port for the cigar, means for lacing a ban adpcent the cigar and artia y wrapping it thereabout, means for nding the ungummed end of the hand against the cigar and means for causm the med end to overlie the ungumme end. As illustrated the latter means is so constructed as to be readily heated and to be 'tion and carried to a position where it lies across the cigar. pressed to the position shown and the sponge rubber strips the ends of the band from 1925. Serial at. 42,450.

nisms can be operated manually or by a y d sired motivepower with suitable connections thereto. It is preferred, however, to operate them by means of the driving elements described in detail in my prior application abovereferredto. a --:-In my-prior application the roller used for c5 bending the ungummed' end of the band was ajcarrier of moisture. With this-invention the supply of moisture can be andpreferably is'omitte Referring now to the drawings by reference numbers, the bench 10 is provided on its upper surface with cradle shaped cigar rests one'of which is shown at 12. A cigar 18 is shown in positionthereon. 7 The drawin shows the lower portion of a head 14 which carries two suction tubes 7 15. The suction tubes have forwardly ex- I tendin 'horizontal portions having suction ports not shown) in their lower surfaces. Held in position by suitable clamps is a block of sponge rubber 17 which forms the lower surface of the head 14.; The head 14 is movable from the positionshown in the drawing to a position over a pile of cigar bands. The uppermostcigar band is lifted by suc- The head 14 is then dethe suction tubes and wraps the band about three sidesof-the cigar. At this time the ends of the band extend downward through an opening in the bench 10 between the su orts 12.

echanism for completing the bandin operation comprises rol ers 20 and 21 which are movable horizontally in paths enabling them to engage'the under surface of the cigar. The normal position of the roller' 20- is'that shown in Figure 1. The normal position of the roller 21 is at the right of the cigar just beneath the guide roller 23.

.The roller 20 is first moved to the right far enough to bend the ungummed end of the band underneath the} cigar. The rollers 20 and 21 are then moved simultaneously to the left to the position shown in the drawing. By this operation the g'ummed end of the band is bent underneath the ungummed end.

The roller 21 is maintained at a sufliciently high temperature to soften the adhesive material on the band and is held against the band with sufficient force to cause firm and rapid adhesion. A convenient manner of applying an upward force to the roller 21, is

to mount it on a jointed arm 25 havin a Spring 26 acting about the pivot of the joint. The preferred way of heating the roller 21 is'shown in Figure 2. The roller .comprises an outer shell 27 and a sleeve 28 on the i f shaft29, all of metal. A sleeve 30 of insulating material surrounds the sleeve 28.

On the insulating material 30 is wound re-. sistance wire 32 of the kind ordinarily used f .in electrical heating units' One end ofthe wire is grounded on the metal portion of the roller and the other end is connected to an insulated ring 34;. Electric current is supplied from a suitable source, such as an ordinary. house ligating circuit, through wires 35 and 36. he 35 is connected to ground and wire 36 is connected through a switch-37 and a rheostat 38 to a brush 39 on insulation 1 arm which makescontinuous contact with the ring 34; The brush 39 is'suitably mounted carried by onefork of the The surface of the roller 21 may be corru gated by providing annular grooves 41, which may be desirable to insure distributed contact with the'band in case oven surface.- 7

While. the invention-1s shown in one embodiment, it obviously can assume otherforms, and certain features of the invention the cigar has an un-.'

can be used for sealing gummed surfaces other than cigar bands. The heated roller may of course be heated by means other than that described herein.

\Vhat is claimed is:

1. In cigar banding apparatus, means for a holding a band partly surrounding a cigar,

said band having adhesive material at one gummed end of the band against the article a and a heated surface for bending the gummed end of the hand upon the other end and press- "ing it thereagainst.

5. In a cigar banding machine, means for placing a band partly about a cigar means for bending'one end of the band'against the cigar, and aheated surface operating to bend the other end' of the band against said first end and to press it thereagainst, the simulta;

neous heat and pressurecd-operating with adhesive material between the band ends to cause firm adhesion.
